President Donald Trump says he has asked the SEC to study whether to stop requiring companies to report quarterly earnings.

In speaking to business leaders, one told him a twice-a-year reporting system would allow companies the flexibility and cost savings companies need to "Make business (jobs) even better in the U.S." Trump tweeted Friday morning. Trump said he directed the SEC to look into a change in its requirements.

"I'd like to see twice but we're going to see," Trump said. "So we're looking at that very very curiously, we're looking at twice a year instead of four times a year."

Public companies must report their sales, profits and the state of the company's balance sheet every quarter. That has been required since the Securities Exchange Act of 1934, which was put in place to give more confidence and transparency to investors in the wake of the 1929 stock market crash. That act also created the SEC, which sets the regulations which govern those quarterly reports.

Businesses have long complained that the reports require company executives to focus too much on the short term. Juicing numbers impresses investors, but it can force companies to miss out on long term trends. One of the reasons Tesla(TSLA) CEO Elon Musk wants to take his company private, he told his employees last week, was the way quarterly reports distort decisions at the company.

In speaking with some of the world's top business leaders I asked what it is that would make business (jobs) even better in the U.S. "Stop quarterly reporting & go to a six month system," said one. That would allow greater flexibility & save money. I have asked the SEC to study!

The SEC has already been working on the issue. Chairman Jay Clayton issued a statement Friday saying the agency "continues to study" reporting requirements, including how frequently companies should announce results.

"The president has highlighted a key consideration for American companies and, importantly, American investors and their families — encouraging long-term investment in our country," Clayton said.

President Barack Obama has also criticized quarterly reports.

Speaking to the New York Review of Books in 2015, Obama said that he had talked to a large number of businesses executives who told him, "Because they've got quarterly reports to shareholders and if they've made a long-term investment that may pay off way down the line, or if they're paying their employees more now because they think it's going to help them retain high-quality employees, a lot of times they feel like they're going to get punished in the stock market. And so they don't do it, because the definition of being a successful business is narrowed to what your quarterly earnings reports are."

Shareholders, however, use the quarterly earnings reports as a guide to the quality and health of their investments. Without quarterly financial reports, investors could be blind to important risk factors that could damage their portfolios.

Nooyi confirmed she had talked to Trump about the change of schedule. She pointed out that it had the support of many CEOs, including the Business Roundtable, an association of leading CEOs.

"Many market participants...have been discussing how to better orient corporations to have a more long-term view. Most agree that a short-term only view can inhibit long-term strategy," she said. "In the end, all companies have to balance short-term and long-term performance."

Studies on the subject are mixed. It's unclear whether management at companies that report semi-annually take a longer-term investment strategy than management at companies reporting quarterly, said Salman Arif, a business professor at Indiana University who has studied the difference in reporting periods. What is clear is that investors are more reluctant to invest with companies when they have less information on their performance.

"Less frequent reporting can raise the cost of capital," he said. "If you're taking away information from investors, they will be desperate for any signals on performance."

He said when companies report only twice a year, the reaction in markets to their results is typically more volatile than the reaction to quarterly results.

The president has run privately-held companies that didn't have to report results at all during most of his time in business.

"This is the most myopic president in history," said hedge fund manager Stan Druckenmiller: "He doesn't think -- in any way -- long term. I find it very rich that he's proposing this with some veil that it's going to help companies think long-term. As an investor, I find it troubling."

Druckenmiller noted that investors like to know what's going on with the companies they invest in. A lot can change in a three-to six-month period, especially with all the disruption in technology.

"You've got guys like Elon Musk saying they want everyone to think long term. In the meantime he's building cars in a tent so he makes quarterly numbers," said Druckenmiller. "Jeff Bezos has proven you can report quarterly numbers and think long-term. He's done it."

The European Commission, among others, only requires semi-annual financial reports of companies there, although major European companies whose stock is traded in both the United States and Europe will report on a quarterly basis in order to comply with SEC regulations. Nooyi said she thinks it would be beneficial to harmonize American and European rules on financial reporting.
